DE4304888A1 - Permeable rigid-plastics mats on car parks, playgrounds or temporarily on large green areas for staging events - Google Patents

Abstract

Car parks are able to breathe and be covered with greenery, likewise playgrounds, do not need to be asphalted over or concreted over, but at the same time can be clean: in the event of rain the water percolates through the mat pores; grass grows through the pores, since the permeable gravel substructure with greasy but loose topsoil layer provide ideal growth conditions for lawn grasses. The problem of asphalt or concrete in public or company places; of pools of water, ground which is trampled and thus may turn to mud, when it rains; of crushed plants, is thus overcome with the invention of the matting. The rigid-plastics mats are perforated to allow the ground to breathe, grass growth, percolating water, sunray absorption, i.e. are permeable on both sides. At the same time, they are able to withstand any loading, being up to 10 cm thick, and also displacement, for instance in winter during snow clearing, as a result of aluminium pegs at the edge of the mat. They should not, however, be gritted or sanded, which would block the pores. To prevent the pores from freezing over, heating coils are provided in the mats, which at the same time are connected to the mat-joining buttons and can be supplied with recovered energy. To delimit the mat area, attachable/detachable rectangular, triangular, curved or corrugated mat pieces are provided. The surface profile is formed from supporting knobs with longitudinal, transverse and diagonal webs, while the underside ... for the purpose of stable support ... with broader supporting knobs ...

Description

Permeable hard plastic mats in parking lots, playgrounds or at short notice on large event spaces in the Greens.

Breathing, lawn-green vehicle parking spaces or playgrounds there are hardly any, but more and more areas are being used for parking concreted; the children and adolescents needed for their natural urge to play and exercise too natural but always clean surfaces.

The risk of being sporty on large meadows and parks or schedule cultural events with unpredictable Rain showers, d. H. Soil softening and silting, Damage to green areas, impairment of clean ones Event, can be calculated by the invention, insignificant.

The advantage of the invention as stated in claim 1 is in that for soil breathing, rain drainage and grass growth required finely perforated, depending on the type and Intensity of stress up to 10 cm thick hard plastic mats are stable in structure and also on not move the lawn or meadow topsoil can cause this depending on the load about 20-40 cm long corrosion-free aluminum anchoring piles at a distance 1.50 m on the edge of the square, at the vehicle parking lot also concreted.

Another advantage in the design of the invention consists in the fact that certain basic parameters, as required, from 1 m by 1 m to transport size 20 m by x m, can also be rolled up for easy flexibility, various Forms are tied on appropriate strips as required can be, with snap fastener, as in claim 2 is specified.

Another advantage of the green area protection mat is in that playgrounds and parking lots are inexpensive because without Sewerage and can be built quickly. Looser, coarse-grained substructure made of wall gravel or similar 15-30 cm, with Vibrators compacted, a permeable fleece layer on top and then a 10-20 cm high greasy topsoil or Humus layer. Rainwater seeps through the mat holes in the ground, there are no puddles of water or dirt, in dry conditions, the grass roots come from below supplied with water via the natural capillary tube system, what claim 3 says.

Conduct so that melt water can seep through in winter Heating coil energy from the heat recovery unit through the mats; the spirals of the individual mat parts are coupled with the metal connection buttons.

Claims (3)

1. Permeable hard plastic mats in parking lots, playgrounds, or at short notice on large event spaces in the green, for natural lawn green, but also clean parking lots and play areas or to protect existing lawn or meadow areas, characterized in that
that the mats for soil breathing, grass growth and leachate are perforated, but have a stable structure for every stress and are anchored against movement by means of aluminum pegs, 20-40 cm long, concreted in at the parking lot edge. 2. Permeable plastic mats according to claim 1, characterized, that to certain basic sizes from 1 m by 1 m to x m to 20 m different shapes can be knotted as required can. 3. Permeable plastic mats according to claim 1 and 2, characterized in that in vehicle parking lot or playground appropriately permeable substructure with permeable fleece allows rainwater to seep through, but the grass roots are supplied with water in dry conditions via natural capillary tubes in the greasy topsoil.
The mats can also be heated in winter; Heating spirals conduct energy from heat recovery or circulation units, they are coupled with the metal connection buttons.
